My invention relates to improvements in bottle or container filling machines and particularly to the filling valve used in conjunction with such a machine.

More particularly, my invention relatesto an improvement in a filling valve of the type wherein there is provided a rotary valve controlling member for controlling the admission of counterpressure to the bottle, to initially exhaust the air therefrom, controlling the admission of the liquid to the bottle and eventually shifting the bottle after the same has been filled.

In certain of the rotary type vvalves for accomplishing the above results, the valve structure is such that the parts have to be made unnecessarily large, thereby increasing considerably the frictional resistance to the turning efiort of the valve and also increasing the valve parts. Y

It is one of the objects of my invention to so construct a valve having the above characteristics that'the parts may be reduced materially in size and the frictional wearing thereby materially reduced, to say nothing of the other more specific advantages.

For the purpose of disclosing my invention, I have illustrated an embodiment thereof in the accompanying drawings in which:

the filling machine includes a filling tank I adapt- I ed to contain the carbonated water with which it isintended to fill the bottle or other container. This container or tank is provided' with suitable float valves 2 and 3 controlling the admission to or the escape of carbon dioxide gas into the top of the tank and above the water contained therein. Water is supplied tothe tank through the medium of a water supply pipe 5, the arrangement being such that the tank and its associated parts can be rotated. Preferably, in this type of filling machine, the admission of water into the tank is controlledby the'counter-pressure of the COz-admitted thereto. It will be noted that with the float of the valve 2 in its lower position, this This tank has mounted thereon a series of filler valves 6 adapted to rotate with the. tank and each being adapted to receive from the tank a supply of liquid through the pipe 1 and a supply of CO2 through the pipe 8. The filling valve,

generally considered, consists of a head 9 having secured thereto a downwardly. extending stem,-l ll.

This stem is flanged as at H at its upperend and receives a coupling nut l2 screw threaded to I the head 9. -The lower end of this stem In receives and supports the filler tube l3 which, in effect, comprises two tubes, the outer tube l4 through which gas is admitted to and withdrawn from the container to be filled and the inner tube I5 which telescopes the outer tube This'inner tube I5 is providedwith a longitudinally extending passage [6 onits outer surface, through which.

the gas may be passed to the bottom of the tube and escape through the openings H in the outer tube.

The lower end of the inner tube is closed by a valve l8.having a seat l9 adapted to engage the bottom end of the tube I5 and provided with an annular flange telescopically receiving the bottom end of the tube and provided with an escape opening 20.

A bottle bell 2| is slidably mounted on the filler tube l3 and at its lower end is provided with a bell-shaped opening 22 to receive the bottle. This bell, in its normal position, is at the lower end of the tube, as illustrated in Fig. 2, but when the bottle is raised through suitable instrumentalities, the neck of the bottle enters the bell mouth, making sealing engagement with the sealing washer 23 and raises the bell 2| until it makis sealing engagement with the sealing washer 2 round the filler tube l3, there being left between the filler tube and the washer, a suitable passage 25, the purpose of which will more fully appear hereinafter.

The liquid delivery pipe 1 makes engagement with the threaded boss 26 on the head 9 and delivers through the opening 2! therein and the hand-controlled valve 28 into the chamber 29 at the top of the head. The gas or counter-pressure 'supp-ly pipe 8 is connected to a similar boss 30 on the head 9 which communicates by the opening 3| with a chamber 32 from which counter-pressure is delivered through the valve to the container.

The filling valve is provided with a valve operator 33 having an upper arm 33' and a lower arm 33". This valve operator is adapted to manipulate the valve mechanism for controlling the admission of counter-pressure to the bottle to be filled, the admission of the liquid to the bottle and the snifting of the bottle after the filling operation has taken place. In machines of this character, the lower arm 33" is adapted to engage suitable stops arranged in its path of movement for the purpose of moving the same into certain predetermined positions. Likewise, the arm 33' is adapted to engage suitable stationary stop, in the path of the movement of the valve, for moving the valve mechanism into certain predetermined positions. The positions to which the arms 33 and 33" are moved are indicated in full and dotted lines in Fig. 2. Referring to this figure, when the arms are in the position shown by full lines, they are in the shifting position. The second position is indicated by the next position to the left in dotted lines as being the counter-pressure position and the final position indicated by the dotted lines is the filling position.

As illustrated in Fig. 4, the pipe 8 and, therefore, the top of the tank I is adapted to be placed into communication with the valve when the bottom of arm 33 is moved, by the engagement with the stop, to the position indicated in Fig. 2 as the counter-pressure position. It will be noted that the chamber 32 is connected by a passage 32' with a face 34 on the head 9. This face, in turn, is connected by a passage 35 in the stem portion of the valve which, in turn, is connected with a passage 36 in the stem portion M which passage 36, in turn, is in communication with the passage IS in the inner tube l5 of the filler tube l3. For controlling communication between the passages 35 and 32', I provide a rotatable valve member 3'! which is rotatably mounted within an annular flange or sleeve portion 38 on the head 9, which valve member is provided with a conduit 39, within its body, in communication with a passage 40, a second passage 4| somewhat reduced in diameter relatively to the passage 40, and with a third passage 4|. In order to insure aliquid tight joint between the face of the rotatable valve member 31 and the face 34 of the head 9, I interpose between these faces a packing disc 42 which may be of leather or other suitable material, and this disc,'it will be noted, is provided with openings therein coinciding with the passages 32 and This bell mouth does not tightly sur- 35. Suitable nipples 43 pass through the openings in the washer and into the passage openings. This rotatable valve member 31 is rotatably mounted upon a spindle 44 in the valve head 9. The valve member 3'! is provided with an annular flange or extension 45 which overhangs a collar 46 surrounding and keyed to the spindle 44. Interposed between this collar and the valve member 3'! is a resilient member in the form of a rubber ring 46' which maintains the packing disc 42 in close contact with the face 34. The collar is moved toward the valve member 31 by a nut 41 screwed on the end of the spindle 44 and by turning this nut up suiiiciently tight, a tight joint is made between the face of the valve member 3! and the packing disc 42. The collar 46 has a pair of radial arms 48 and 49. The arm 48 is arranged in a slot 50in the hub of the lever 33 and the arm 49 extends between a pair of bosses 5! on the annular flange 45 of the valve member 31. Suitable adjusting screws 52 extend through these bosses and bear against the arm 49 so that a nice adjustment of the relationship between the disc 31 and the operating member 33 may be obtained. This arrangement provides a driving connection between the operating member 33 and its associated arms 33 and 33" and the spindle 44 and valve member 31, whereby the spindle 44 and the valve member will be rotated in unison with the operating arms.

In addition to the passage 36, the stem ID and associated part 9 has a passage 53 likewise communicating with the top of the gassing tube 3 through passages 39 and 53, which passages in the filling position of the valve are adapted to be placed in communication with the port or opening 4| and thereby, as is the case in the counterpressure position, placing the bottle in communication with the top of the tank I and therefore in communication with the counter-pressure zone. The establishment of this communication takes place when the valve has been rotated to the furthest movement, as indicated in Fig. 2 in dotted lines, to the filling position.

The valve member l8, for controlling the fiow'of liquid through the tube I5 is operated through the medium of a stem or rod 54 which extends upwardly through said tube and terminates at its upper end in a cap 54 threadedly mounted on the rod. Interposed between this cap and a shoulder 55 is a coiled spring 56 which biases the valve in its closed position. The chamber 29 communicates through the passageway'29' in the head 9 with the tube '|5 and arranged in this chamber is a valve 51 biased in its closed position by a coiled spring 58 which tends to move the valve downwardly and on its seat 59. When so seated, communication from the chamber 29 is closed to the passageway 29'. The valve 51 is provided with a downwardly extending stem 60 which extends toward the cap 54.

Interposed between the cap 54' and stem 69 is a cam member consisting of a pair of radial arms 6| and 62 mounted on the spindle 44. These arms are adapted to respectively contact with a pair of swinging members 63 and 64,

the ends of which are interposed between the cap 54 and the stem 60 so that when the cam member, with its arms 6| and 62, is in one position, both of the valves 51 and I8 are opened, and when in their crosswise position, these valves are closed. The timing is such that the valves are moved to their open position at the same time that communication is established between the passage 53 and the port 4|. Therefore,

when the valves 51 and I8 are in their open position to permit the fiow of liquid from the tank intothe bottle, the counter-pressure tube is placed in communication with the top of the tank and the gas heretofore introduced into-the bottle is allowed to flow back into the tank.

After the bottle has completed its rotative movement with the tank I until it has become filled, the upper arm 33' of the operating lever 33 engages a stop, arranged. in the path thereof, moving the upper arm torotate the valve member in a counter-clockwise direction, therefore closing the filler valve and the counter-pressure passages. At the same time the passage 65, in communication with the top of the bell 2! is placed'in communication with a sniit passage 65' leading to the atmosphere through the medium of a passage 86 in the valve member 37 and a pair of ports 61 and 68.

It is apparent, from the above structure, that the number of ports to be controlled by the rotary valve member 37 is reduced to the minimum because the liquid control valve which under certain commercial circumstances heretofore in practice has also been controlled through this rotatable valve member is now controlled by the pair of valves i8 and 5'! operated in turn by the cam members 6i and 62.
